Title: Method of reducing axial beam focusing
Inventor: BERGSTROM JAN OLOF
IPC: H05H7/04
Filed: 1999-09-28
Abstract: A method is disclosed for minimising the diameter of the magnet poles of a cyclotron system for production of radioactive tracers. The method selects a n operation mode having ~z defined below the critical resonance value of ~z=1/ 2 and chooses a valley technique having shallow valleys by selecting a first magnet pole parameter defining a valley gap accepting a narrow spaced RF electrode system and size facilitating a vacuum conductance necessary for obtaining a low enough pressure. The method then defines a second magnet pol e parameter by setting a sector gap size. The magnetic azimuthal field shape i s transformed from being "square-wave"-shaped to becoming approximately sinusoidal by increasing the magnetising field. Then an average magnetic fie ld is calculated from the increased magnetising field and the first and second magnet pole parameter. A pole diameter can then be established to obtain a most compact design of the electromagnet for a cyclotron system. A cyclotron  system in accordance with the method is also disclosed.

Title: Graphics system having a super-sampled sample buffer with generation of output pixels using selective adjustment of filtering for implementation of display effects
Inventor: DEERING MICHAEL F
IPC: G06T15/00
Filed: 2000-02-17
Abstract: A computer graphics system that utilizes a super-sampled sample buffer and a programmable sample-to-pixel calculation unit for refreshing the display, wherein the graphics system may adjust filtering to reduce artifacts or implement display effects. In one embodiment, the graphics system may have a graphics processor, a super-sampled sample buffer, and a sample-to-pixel calculation unit. The graphics processor renders a plurality of samples and stores them into a sample buffer. The sample-to-pixel calculation unit reads the samples from the super-sampled sample buffer and filters or convolves the samples into respective output pixels which are then provided to refresh the display. The sample-to-pixel calculation unit may selectively adjust the filtering of stored samples to reduce artifacts, e.g., is operable to selectively adjust the filtering of stored samples in neighboring frames to reduce artifacts between the neighboring frames. The filter adjustment may be applied where the sample-to-pixel calculation unit generates output pixels at the same rate as the graphics processor rendering samples to the sample buffer, or at a different (e.g., higher) rate than the render rate. The sample-to-pixel calculation unit is operable to adjust filtering of stored samples to implement a display effect, such as panning, zooming, rotation, or moving scenes, among others. The sample-to-pixel calculation unit may also selectively adjust the filtering of stored samples on a fractional-pixel boundary.

Patent CA-2364638-A1 (CA)
Inventor: COPPOLA VINCENZO
IPC: B22D17/20
Filed: 2001-12-06
Abstract: An improved injection molding machine having a support frame, an injection gun, a guiding device, and a molding cavity, the guiding device being mounted to the support frame for moving the injection gun along a longitudinal axis towards and back from the molding cavity. The improvement lies in that the guiding device includes an actuator, a lever link, a coupling link, and a guiding track. The actuator is mounted to the support frame and has a piston end movable between a retracted position and an extended position. The lever link has a central portion pivotally mounted to the support frame and further includes first and second ends located respectively on both sides of the central portion, the first end of the lever link being pivotally connected to the piston end of the actuator. The coupling link has a first end pivotally connected to the second end of the lever link and a second end pivotally connected to a connection point of the injection gun, the coupling link being disposed substantially in parallel to the longitudinal axis. The guiding track is mounted to the support frame in such a manner as to extend along the longitudinal axis and cooperates with the injection gun for guiding the same along the longitudinal axis. The guiding device is devised so that a displacement of the piston end of the actuator between the retracted position and the extended position operatively moves the injection gun by means of the links and guiding track towards the molding cavity whereby the injection gun is in injection position and back from the molding cavity wherein the injection gun is in a rest position. The injection molding machine with the above-mentioned guiding device enables a decrease in molding material splashings and improved molding results. The guiding device may be mounted and dismantled very easily for quick and easy maintenance and/or part replacement of the machine.

Title: Fuel injection control system, fuel injection control method, and engine control unit, for internal combustion engine
Inventor: TAKIZAWA OSAMU
IPC: F02D41/02
Filed: 2002-01-16
Abstract: There are disclosed a fuel injection control system, a fuel injection control method, and an engine control unit for an internal combustion engine, which are capable of accurately controlling a fuel injection amount according to changes in a valve overlap period due to changes in a cam phase, thereby ensuring proper engine performance. The fuel injection control system for an internal combustion engine which is capable of changing a valve overlap period by changing a cam phase includes an ECU. The ECU calculates a cam phase difference between the present value and the immediately preceding value of the cam phase (amount of change in the valve overlap period), calculates a wall surface temperature of intake ports, and sets a basic fuel injection time period based on an intake pipe absolute pressure and an engine rotational speed. The ECU calculates a final fuel injection time period by correcting the basic fuel injection time period according to the cam phase difference and wall surface temperature of the intake ports.
Patent CA-2367887-A1 (CA)
Inventor: WOODS JOHN T
IPC: F03G7/10
Filed: 2002-01-11
Abstract: In previous efforts to construct a weight motor, 'equal and opposite' reactions have thwarted success. In the design of this motor, two shafts with fixed journal box positions, and their respective wheels, flank a middle 'floating' shaft and its wheels, and through their unequal positions of support, split the force into a dominant force (which determines the order of rotation) and a recessive force, which must follow the dominant order. On the middle float shaft are two gears: one with a very small diameter, and a second which is very large when compared to the first. Both gears travel in unison around the floating shaft. On one side of the floating shaft is an extremely large gear which engages the smaller of the two floating gears. The apparent weight (whether gravitational, or induced by some other directional force) of the middle shaft assembly imposes pressure against the periphery of the large outer gear, causing it to rotate away from the float assembly. Paired with the large outer gear is a similarly large sprocket which sends its rotational power to a much smaller sprocket on the opposite flank of the middle floating assembly via a transfer chain. The small 'hub' sprocket rotates in unison with a large gear fixed to the same shaft. The ratio of the hub sprocket to its complementary large gear is the same as the ratio of the small inner floating gear to its large outer counterpart. The torque which is generated by the extremely large wheels on one side of the system are enough to force the power through the system as continuing rotational energy, such that the small middle gear is forced to continue to 'climb' the largest gear, producing the required harmony of rotations throughout the system and holding the middle assembly to a relatively fixed attitude of engagement. Because the extremely large wheel on one side of the floating system supports more of the pressure exerted against the floating assembly than does the small opposite wheels assembly, it is able to send surplus rotational energy through the system, such that power may be drawn off one or more of the wheels, and/or the system may be allowed to accelerate. The motions and forces generated can be perpetuated so long as the same directional pressure is exerted against the middle shaft. If the pressure is reversed, the directions of all wheels and chain reverse also. Thus we see that the device is not strictly a weight motor, as artificial 'weight' can be induced from any attitude of system placement - whether in a strong gravitational field or not, whether in space, or in air, or in water, or in some other fluid medium -there needs not be an 'up' and 'down.'
